The next logical step on the "drunkness" scale, immediately following "Hammered" but antecedent to "Blackout." An individual who is "Abbydrunk" is most often characterized by one or more of the following symptoms: excessive laughter and/or screaming, whether it be directed at something in particular or not, theft of clothing, inability to walk/stand/run/formulate sentences properly, destructiveness--although for some reason only affecting objects or property belonging to the "Abbydrunk" individual, or narcoleptic-like bouts of unconsciousness most likely brought about by the smoking of cigs and/or other substances.
